A somewhat anachronistic slang term for "bitch" that is currently used mainly in the context of self-conscious irony. Can be traced to the early 1990s, when rappers, responding to the copious bleeps and silences placed on their radio and video singles, began replacing the offending words with the same sound clips played backwards or in a highly manipulated fashion. The resulting vocalizations could be very loosely approximated by inserting a "z" sound into the middle of the word, and many rappers began to simply employ this technique with their own voices. Manipulations such as "biznatch" soon entered the slang world. Eventually, rappers such as Snoop Dogg would popularize the practice of manipulating even innocent phrases in this fashion, such as "fo' shizzle" (for sure). By this point, most had forgotten the origins of this strand of slang.

A replacement mainly used by highschoolers to replace the word Bitch...Using the term this way can sumtimes be accepted by teachers..parents..or other adults or faculty...Biznatch can be said jokingly to friends
